"Second home" mortgages

[Tim Schroeder]

My first property was a "second home" mortgage with 15% down. I've since refinanced that loan and bought additional properties with standard 20%-down "investment" mortgages. The question is, when (if ever) can I say, "This property is no longer a second home, it's an investment" and then get a new "second home" loan on a new property purchase? (Note: I already know I can get another "second home" loan in a different geographical location. I am talking here about multiple properties in a single small area). I guess I'm trying to "recycle" my second home low-down-payment benefit and use it again.
